vSpecification forming part ofLetters Patent Nol-198,50, dated December 25, 1877; application filed .l A, `v December3, 1877. l

hereby declare that the following is a full,

clear, and exact descriptionthereo which enable others skilled in the art tol which it appertains to make and use the same, reference being had' to the accompanying drawings, andto letters of reference marked thereon, which form apart of this specification. My inventionlrelates `to improvements in machines for automatically settingnailsin boot ori-shoe sole or heel forms, or setting nails directlyfinto perforated ,heelsor soles for boots and shoes; and myinvention con'- sistsin mechanism f-by whichffthe-,nails that are laid upon the receiving-table are kept in .constant circulation till they vare singly delivered into receiving-throatsl and conducted to the heelfform or perforated .heel-blank, by which arrangementone nail only is delivered at a time lto )each o f the receiving-throats, and the balancent. the.nailskept` in a constant circulation till requiredfor deliveryinto the said throats or receivers.

My invention also relates to, .mechanism by which the nails are .automatically headedthat is, .arranged in such amanner as to. be conducted toward the a .receivin g.- throats, all in -one and-the same positions-.that is to say, so aste lay allthelnails so, that they shall be presented with their-points downward.

My invention further relatesli-O mechanism by .which the .headed nailsy .are collected in pools, fromv which, they are lifted, and,` delivered into theconductors leading .tothe heel,-

blank or perforated heel-forms. Y Y My inventionfurtherl relates .to thecombination, in a .nail-setting machine, as .above named, of nail-deliverers, a stationary guideblock, and iiezrible` conductors .for the nails from the .deliverersfto the perforations in the guide-blocker heel-blanks.

,'Myjinventionv lso relates to mechanism which ,a longitudinal reciprocating motionris imparted to the nail-carriers of which the receiving-ta'ble is composed, for the purpose of feeding nails one by one to each of the receivers, and to circulate the remaining nails till required for use.

Myinvention also relates to a nail-carrier for nail-setting machines, having a converging feed-groove and a diverging waste-groove, and a waste-vent, through which the superiiuous nails escape, to be circulated until required for feed to the receiver.

f In the accompanying drawings, Figure 1 represents a front elevation of my invention; Fig. 2, a plan view of the same; and Fig. 3, a l side elevation of the machine, seen from the right.4 Fig. 4 represents a plan view of the nail throats or receivers, and Fig. 5 a front view of Fig. 4. Fig. 6 represents alplan view of one ofthe nail-carriers, in which the wastegroove and waste-vent, as well as the heading mechanism, are located; and Fig. 7, a side elevation of the said carrier, and the mechanism by which the longitudinal reciprocating motion thereof is imparted from the rotary shaft of the machine. Fig. 8 represents an end view of the said carrier, seen from its forward end.. Fig. 9 shows a side elevation of the driving-shaft, balance-wheel, and corrugated `roller for imparting the reciprocating rnotiontol the carriers.` Fig. 10 shows a side view of one of the lifters by which the nails are.taken singly from the pools. and delivered to the throats or conductors. Fig. 11 shows anV end view ofthe said lifter. Fig.

12 represents a plan view of one'of the carriers, inwhich the receiving-throat is located, as well as the perforation for the vertical guidance of the laforesaid lifter. Fig. 13 represents a side view of the same. Fig. 1 4 represents an end view of the said carrier, seen from its .forward end. Fig. 1 5 represents a plan view of the perforated guide-block, and Fig. 16 represents a similar plan view of the perforated nail-form into which the nails are delivered. Fig. 17 represents a side view of the flexible spiral-wire conductors for the nails.

Similarletters refer to similar parts wherever they occur on the different parts of the drawings.

Ain Figs. 1 and 2 represents the receivingtable, on which the nails are scattered promiscuously.` This table is composed of a series of bars erf-carriera a c afb b b, arranged-inpairs,

the rotary shaft c, on which is secured a corrugated roller d, that rotates between a pair of spring-bars, e e', secured to the lower frame of the machine by means of thumb-screws ff, or similar devices. The upper ends of the spring-bars e c are connected to horizontal cross-bars g g', playing in recesses h h', made in the under side of the carriers a a b b, as shown in Figs. 7 and 13. Itwill be seen by reference to said figures that the bar g fits snuglyin the recess h, (shown in Fig. 7 which is the rear recess, and that the bar g' iits snugly in the recess h', (shown in Fig. 13,) which is the front recess, and that the forward recess h' in Fig. 7 is larger than its corresponding bar g', and also that the rear recess hin Fig. 13 is larger than its corresponding bar g, which is done for the purpose of imparting a quick blow from the front to the rear of the bars b b, and easing oif their'return motion, at the same time as a quick blow from the rear to the front is given to the bars a a, with an easy and soft return motion in the opposite direction. By these means the nails are kept in a motion, as shown by the arrows in Figs. 2, 6, and 12-tl1at is, from the front to the rear on the carriers a a a, and vice versa on the carriers b b b.

The reciprocating carriers a a a, are each composed of =the following elements, viz: a pool, in which the nails are collected after being turned or headed, all in the same direction 5 a perforation, k', through which the lifter 7c moves'up and down for the purpose of taking a single nail at a time from the pool 'i and depositing it into the throat or receiver l, which delivery is accomplished from the rear to the front by the reciprocating motion of said carriers a a a and their lifters k k k. Each carrier a a a is'also provided with a descending plane, m, descending from the side of the pool posed of the following `elements viz: a con-4 verging groove, p, that descends from the rear of the machine toward the central part of the carrier, where it terminates as a single-nail groove, q, that is only wide enough to allow one single nail to pass at a time. To the right of the converging groove p is a waste or overflow divergin g groove, r, that terminates as a wastevent, s s, through which the superfluous nails are allowed to escape upon the ascending plane of the carrier a, to be again circulated. From the single-nail groove q the nails are carried to the heading or turning mechanism, for the purpose ofturnng all the nails with their heads in one and the same direction-viz.,to the front of the machine. This heading mechanism consists of the quarter-turn hole t, (shown in Figs. 6 and 7,) into which the nails that progress with their heads foremost drop down head foremost directly on the feed-channel u, leading to the pool z' on the carrier a. The nails that progress toward the hole t with their points foremost are carried automaticallybeyond the said hole, and when carried far enough the heaviest portion of the nail-that'is, the head portion-drops down first, and in this manner all the nails are delivered upon the feed-channel u with their heads all pointing toward the front of the machine.

For the purpose of preventing such nailsV that for any reason should not be properly turned or headed from dropping onto the feedchannel u, I provide the header or turner with a projecting side-tapering piece, fv, (shown in Figs. 7 and 8,) by which such nails are guided onto the carrier a, to be again circulated, as before described.

The lifters 7c k are each provided with a groove, k", in their upper ends, as shown in Fig. 11, into which the nail is gathered from the pool 'i previous to and during its delivery into the throat or receiver l.'

The lifters k k k are each jointed in their lower ends to the rods lw w, secured in their lower ends to the cross-bar attached to the upright movable guide-posts y y.' 'lhe lower ends of the posts y y are each jointed to the levers z z, having fulerums 1 1, and are rocked by means of the rotary cranks 2 2, having pins 3 3, playing through slotted'holes 4 4 i'n the rear of the levers z z.

The lifters 7c k may, however, be operated in any other suitable manner without departing from the spirit of my invention.

5 5 5 represent the iiexible conductors from the throats l l lto the perforations 6 6 6 (shown in Fig. 15) in the guide-block 7. These conductors 5 5 are made flexible and in the form of coiled wires, as shown in Fig. 17, by which they can easily be moved nearer together or farther away in their lower ends, so as to t y into any desired pattern on the guide-block 7.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1. In a nail-setting machine for boots and shoes, a nail-receiver, A, consisting of the 1ongitudmally-reciprocating bars-or carriers aa a b b b, upon which the nails are continually circulated until delivered into the throats l l Z, substantially as and for the purpose set forth and described.
